IP Tables Question
Greetings:Given the source IP of 80.142.77.210
If I want to block the entire range of 80.142.77.0 through 80.142.77.255 do I use 80.14.77.0/24 as the IP address as part of destination and source?
If I want to block the entire range of 80.142.0.0 through 80.142.255.255 what would I use?
If I want to block the entire range of 80.0.0.0 through 80.255.255.255 what would I use?
Thank you.
